A luminous stellar outburst during a long-lasting eruptive phase first, and then SN IIn 2018cnf
A. Pastorello, A. Reguitti, A. Morales-Garoffolo +45
We present the results of the monitoring campaign of the Type IIn supernova (SN) 2018cnf (aka ASASSN-18mr). It was discovered about 10 days before the maximum light (on MJD = 58293…
Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm
G. Terreran, M. L. Pumo, T. -W. Chen +41
We present our study of OGLE-2014-SN-073, one of the brightest Type II SN ever discovered, with an unusually broad lightcurve combined with high ejecta velocities. From our hydrody…
On the diversity of super-luminous supernovae: ejected mass as the dominant factor
M. Nicholl, S. J. Smartt, A. Jerkstrand +37
We assemble a sample of 24 hydrogen-poor super-luminous supernovae (SLSNe). Parameterizing the light curve shape through rise and decline timescales shows that the two are highly c…
SN 2009ip at late times - an interacting transient at +2 years
Morgan Fraser, Rubina Kotak, Andrea Pastorello +31
We present photometric and spectroscopic observations of the interacting transient SN 2009ip taken during the 2013 and 2014 observing seasons. We characterise the photometric evolu…
Interacting supernovae and supernova impostors. SN 2007sv: the major eruption of a massive star in UGC 5979
L. Tartaglia, A. Pastorello, S. Taubenberger +15
We report the results of the photometric and spectroscopic monitoring campaign of the transient SN 2007sv. The observables are similar to those of type IIn supernovae, a well-known…
On the progenitor of the Type Ic SN 2013dk in the Antennae Galaxies
Nancy Elias-Rosa, Andrea Pastorello, Justyn R. Maund +7
We report the results of our search for the progenitor candidate of SN 2013dk, a Type Ic supernova (SN) that exploded in the Antennae Galaxy system. We compare pre-explosion Hubble…
The death of massive stars - II. Observational constraints on the progenitors of type Ibc supernovae
John J. Eldridge, Morgan Fraser, Stephen J. Smartt +2
The progenitors of many type II core-collapse supernovae have now been identified directly on pre-discovery imaging. Here we present an extensive search for the progenitors of type…
SN 2009md: Another faint supernova from a low mass progenitor
M. Fraser, M. Ergon, J. J. Eldridge +21
We present adaptive optics imaging of the core collapse supernova (SN) 2009md, which we use together with archival \emph{Hubble Space Telescope} data to identify a coincident proge…
The Disappearance of the Red Supergiant Progenitor of Supernova 2008bk
Seppo Mattila, Stephen Smartt, Justyn Maund +2
Massive stars end their lives in spectacular supernova explosions. Identifying the progenitor star is a test of stellar evolution and explosion models. Here we show that the progen…
Optical and near infrared coverage of SN 2004et: physical parameters and comparison with other type IIP supernovae
K. Maguire, E. Di Carlo, S. J. Smartt +22
We present new optical and near infrared (NIR) photometry and spectroscopy of the type IIP supernova, SN 2004et. In combination with already published data, this provides one of th…
SN 1999ga: a low-luminosity linear type II supernova?
A. Pastorello, R. M. Crockett, R. Martin +11
Type II-linear supernovae are thought to arise from progenitors that have lost most of their H envelope by the time of the explosion, and they are poorly understood because they ar…
SN 2008S: an electron capture SN from a super-AGB progenitor?
M. T. Botticella, A. Pastorello, S. J. Smartt +31
We present comprehensive photometric and spectroscopic observations of the faint transient SN 2008S discovered in NGC 6946. SN 2008S exhibited slow photometric evolution and almost…
A low energy core-collapse supernova without a hydrogen envelope
Stefano Valenti, Andrea Pastorello, Enrico Cappellaro +14
The final fate of massive stars depends on many factors, including mass, rotation rate, magnetic fields and metallicity. Theory suggests that some massive stars (initially greater…
